Nneɛma anan na ɛkyerɛ PTFE ntama a ɛyɛ hyew a ɛkorɔn a wɔde kata so pɛpɛɛpɛ: nea wɔde kata so (particle size 0.15-0.35 μm, viscosity, solid content), coating & sintering process (blade coating a wɔpɛ ma biakoyɛ), substrate su (weave pattern, pre-treatment), ne production environment (20-25°C, <60% RH). Dip + blade a wɔaka abom nhyehyɛe no kari pɛ wɔ penetration ne surface smoothness.
